How to ZIP an entire folder in PHP, even the empty ones?

Question

I'm trying to download a zip from a folder that i have on my app (Laravel 5.8), it's working but they skip all empty folders, and I need them in the zip.

I already tried ZipArchive (php) and chumper/zipper from composer.

Any idea of how can i do this?

This is a Linux Server, running MySQL 5, PHP 7.2 and Apache2.

$files = glob($folder_path);
\Zipper::make($folder_path.'/'.$folder_main_name.'.zip')->add($files)->close();

This lib only accepts glob, but if you have any solution that works, i can easily abandon this.

Answer 1

// Initialize archive object
$zip = new ZipArchive();
$zip->open($zipFilename, ZipArchive::CREATE | ZipArchive::OVERWRITE);

// Create recursive directory iterator
/** @var SplFileInfo[] $files */
$files = new RecursiveIteratorIterator(new RecursiveDirectoryIterator($rootPath), RecursiveIteratorIterator::LEAVES_ONLY);

foreach ($files as $name => $file)
{
    // Get real and relative path for current file
    $filePath = $file->getRealPath();
    $relativePath = substr($filePath, strlen($rootPath) + 1);

    if (!$file->isDir())
    {
        // Add current file to archive
        $zip->addFile($filePath, $relativePath);
    }else {
        if($relativePath !== false)
            $zip->addEmptyDir($relativePath);
    }
}

// Zip archive will be created only after closing object
$zip->close();

Hi. I modified the previous answer and now I get the zip file including the empty folders. I hope this helps.
